The talk aims to cover the latest developments in an environmentally-friendly plasma electrolytic oxidation (PEO) ceramic coating technology for light metals. It will present the benefits of the high performance coatings in terms of corrosion, wear and thermal protection; protection against cold welding, thermal management and low reflectance. Results from various space qualification tests, corrosion and wear data are presented. Success stories on flight missions for NASA, ESA, JAXA and Airbus works will be discussed. Attempts on comparisons with some other oxide coatings such as thermal spray and anodising will be made. Coating applications including automotive, aerospace, oil & gas, biomedical and semiconductor will be briefly touched upon.
